Webby Webby

First of all, this is my first time working with Webby. I have just installed the 0.9.4 gem in the usual manner. I started out (as I tend to do) by exploring the options available to me. These are the commands I ran and the results they gave:

webby -v => Webby 0.9.4
webby --help => normal-looking help
webby -o => Sitefile not found (RuntimeError)
webby -D => Sitefile not found (RuntimeError)
webby -P => Sitefile not found (RuntimeError)
webby -T => Sitefile not found (RuntimeError)
webby . => Sitefile not found (RuntimeError)
webby --options => Sitefile not found (RuntimeError)

At this point I was almost ready to give up, but I did some searching and found the source code that was generating this error. From that I finally figured out that I need a file in (I'm guessing here) the target directory. Running touch Sitefile seems fixed the issue. At lease it allowed me to run the above commands without throwing an error.

So my question is, so long as we are generating files, why not just create an empty Sitefile if one doesn't exist? If not webby should at least print a helpful error message to inform the user. For instance this friendly message could easily do the trick:

Hey! We need a file called Sitefile to exist before doing anything else. Mind you, this file doesn't actually need to have anything in it, but Webby isn't going to do anything useful until this file is created. Try running touch Sitefile to fix this problem.
